My invention relates to metal tension members or bars used in metal eonrete ronstrurtions and the obje. t ol the invemion is to provide a barol' su= h shape as will prevent slipping or moyement between the bar andthe (onrete surrounding it and ot sueh cross se tion as (an be easilyand eheapl rolled in making the bar.

A further objei t of the invention is to provide a bar ol substamtiallunll'orm irossseetional area. throughout its length brwhi h the maximumstrength of the metal in the bar is utilized.

in Figs. 1,2 and 3,1 show a bar ha in; a rertangular body portion 3, twosides of the other tw sides haying flanges i. t proie ting outwardlywith their outer edges (01TH- gated, the top 5 ol the corrugation on oneof the dges being opposite the bottom t; of the iorrngation on theopposite ed ln l igs. 4, 5 and (3, the bar h"; a.
